HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 549, 678, 750 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 549, 678, 750 is 3 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 549, 678, 750 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 549, 678, 750 is 3.
HCF(549, 678, 750) = 3
HCF of 549, 678, 750 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 549, 678, 750 is 3.
Highest Common Factor of 549,678,750 is 3
Step 1: Since 678 > 549, we apply the division lemma to 678 and 549, to get
678 = 549 x 1 + 129
Step 2: Since the reminder 549 ≠ 0, we apply division lemma to 129 and 549, to get
549 = 129 x 4 + 33
Step 3: We consider the new divisor 129 and the new remainder 33, and apply the division lemma to get
129 = 33 x 3 + 30
We consider the new divisor 33 and the new remainder 30,and apply the division lemma to get
33 = 30 x 1 + 3
We consider the new divisor 30 and the new remainder 3,and apply the division lemma to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 549 and 678 is 3
Notice that 3 = HCF(30,3) = HCF(33,30) = HCF(129,33) = HCF(549,129) = HCF(678,549) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 750 > 3, we apply the division lemma to 750 and 3, to get
750 = 3 x 250 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 750 is 3
Notice that 3 = HCF(750,3) .
